问题 During a European broadcast in 2002, television viewers were (i)______by a border collie’s ability to correctly retrieve specific toys at the request of its owner and, subsequently, researchers discovered that the dog had the(ii)______ level of a three-year-old child.

选项

Because the dog was found truly to have an unexpectedly high intelligence level, "awestruck" is the appropriate choice for the first blank.
